I want to play a Dragonborn Sorcerer.
Isn't sorcerer a bit underpowered in 5e? Specially regarding archetypes?
Don't know, but a Dragonborn Sorcerer (Draconic Bloodline.) I can be a half and half dragon type. Gold and Blue. Fire Breath and Lightning Breath, Plus I will get wings.

[ I play for the Roleplay. ]
